TopDo foxes kill and eat their young?
It is not that common, but it does happen. If more than one vixen in a group breeds, the litter of the subordinate vixen is sometimes (but not invariably) killed, either by her or the dominant vixen. The cubs are then often eaten. Very rarely, a vixen may kill the cubs of a vixen living on an adjacent territory and bringing them back for her own cubs to eat.
